	You have recursion: repeat calls main and main calls repeat...
Eventually you may fill the call stack. (I'm presuming Python 3.x -- I
still run 2.x as some of the libraries I most rely upon have not yet been
ported).

	Also the structure

	else:
		return
	<end of procedure>

is equivalent to just

	<end of procedure>


	Let's see... (Untested)
-=-=-=-=-=-
letters='abcdefghijkl'
def main():
	while True:
		ltr = raw_input("Guess a Letter> ")
		if ltr.lower() in letters:
			print "OK, that letter was in 'letters'"
		else:
			print "asda is a UK grocery chain"
		ans = raw_input("Want to try again? ")
		if not ans.lower().startswith("y"): break

if __name__ == "__main__":
	print "How ya doin'"
	main()
